Previously, various control strategies have been used to control aflatoxicosis but there is need to use common alternative strategies to reduce the impact of aflatoxicosis. Therefore, the present study has been planned to check the binding efficiency of different binders such as chitosan, glucomannan and bentonite in nanomaterials and nanocomposites form in <em>in-vitro</em> medium to aid in adsorption of aflatoxins. Initially, the chitosan nanoparticles (CS-NP) and chitosan based nanocomposites, including glucomannan-loaded (GM-CSNP) and bentonite-loaded (BN-CSNP) were prepared and characterized for their morphology using scanning electron microscopy (SEM), zeta sizing, poly dispersity index (PDI), zeta potential and Fourier transform infrared spectroscopy (FTIR). An <em>in-vitro</em> gastrointestinal model for poultry was designed to assess the efficacy of three adsorbents (CS-NP, GM-CSNP and BN-CSNP) against AFB1. The model simulated two distinct pH conditions: the gizzard and proventriculus (pH 3.3) and the small intestine (pH 6.6). These adsorbents were tested at three different doses (10, 15 and 20 mg) for 100 ppb AFB1. Similarly, for 200 ppb AFB1 two concentrations of adsorbents 25 and 30 mg were used. Results of <em>in-vitro</em> experiments showed that all three nanomaterials (CS-NP, GM-CSNP and BN-CSNP) have binding with the AFB1.

However, the functional properties of <em>P. mangshanensis</em> venom have yet to be comprehensively characterised. In this study, we conducted an in-depth analysis of its biochemical activities using a broad panel of in vitro assays. We evaluated protease, phospholipase A<sub>2</sub>, Factor Xa-like, thrombin-like, and plasmin-like activities, alongside assessments of haemolytic and cytotoxic effects. The venom exhibited pronounced Factor Xa-like, thrombin-like, and plasmin-like activities (maximum 66.7 %, 112.1 %, and 51.9 %, respectively), but moderate protease activity (maximum 46.7 %) and low phospholipase A<sub>2</sub> activity (maximum 9.9 %). In contrast, haemolytic activity was virtually absent. Cytotoxicity was assessed in two epithelial cell lines, MDCK II and Calu-3, with a response observed only in Calu-3 cells, which remained low (&lt;19 %). Overall, our findings are consistent with the severe haemotoxicity reported following envenomation by the Mangshan pit viper, and highlight the venom's disruptive effects on the blood coagulation cascade. This characterisation enhances our understanding of the functioning of <em>P. mangshanensis</em> venom, and may support the development of more effective treatment for envenomation by this species.</div></div>","PeriodicalId":23289,"journal":{"name":"Toxicon","volume":"266 ","pages":"Article 108530"},"PeriodicalIF":2.4,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144812451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
